4. Rotate the drive pinion using Tool. Rotating torque should be
equaltothereadingrecordedinstep4aboveduringremoval
plus an additional 0.56 N·m (5 in-lb).
5. If the rotating torque is low, continue to tighten the drive pinion
lock nut in 6.8 N·m (5 ft-lb) increments without overtightening.
Refer toRFD-15, "
COMPONENTS". Tighten until proper rotat-
ing torque is achieved.
CAUTION:
lDo not loosen the drive pinion lock nut to decrease drive
pinion rear bearing rotating torque.
lDo not exceed specified rotating preload torque. If preload torque or rotating torque is exceeded
a new collapsible spacer must be installed.
lDo not exceed maximum tightening torque. If maximum tightening torque is reached prior to
reaching the required rotating torque, the collapsible spacer may have been damaged. Replace
the collapsible spacer.
6. Check the gear oil level. Refer toRFD-9, "
Checking Differential Gear Oil".
7. Install the remaining components in the reverse order of removal.Tool number : ST3127S000

ASSEMBLY INSPECTION AND ADJUSTMENT
lBefore inspection and adjustment, drain gear oil.
Total Preload Torque
1. Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
2. Rotate drive pinion at least 20 times to check for smooth operation of the bearing.
3. Turn drive pinion in both directions several times to set bearing
rollers.
4. Measure total preload with preload gauge.
NOTE:
Total preload torque = Pinion bearing preload torque + Side bearing preload torque
lIf measured value is out of the specification, disassemble it to check and adjust each part. Adjust pinion
bearing preload and side bearing preload.
Adjust pinion bearing preload first, then adjust side bearing preload.
Tooth Contact
Checking gear tooth contact pattern is necessary to verify correct relationship between drive gear and drive
pinion. Gears which are not positioned in proper arrangement may be noisy and/or have a short life. Check
gear tooth contact pattern to obtain the best contact for low noise and long life.
1. Remove carrier cover. Refer toRFD-13, "
Removal and Installation".
2. Thoroughly clean drive gear and drive pinion teeth.
3. Apply red lead to drive gear.
CAUTION:
Apply red lead to both the faces of 3 to 4 gears at 4 loca-
tions evenly spaced on drive gear.Tool number : ST3127S000
To ta l p r e l o a d
Gear ratio 3.357 Type:
2.38 - 4.46 N·m (0.25 - 0.45 kg-m, 21- 39 in-lb)
Gear ratio 3.538 Type:
2.34 - 4.34 N·m (0.24 - 0.44 kg-m, 21- 38 in-lb)
Gear ratio 3.692 Type:
2.32 - 4.34 N·m (0.24 - 0.44 kg-m, 21 - 38 in-lb)
When the preload torque is greater than specification
On pinion bearings: Replace collapsible spacer.
On side bearings: Loosen side bearing adjuster.
When the preload torque is less than specification
On pinion bearings: Tighten drive pinion lock nut.
On side bearings: Tighten side bearing adjuster.

4. Hold companion flange steady by hand and rotate drive gear in
both directions.
5. If outside the standard, adjust drive pinion height adjusting washer and backlash. Refer toRFD-23, "
Drive
Pinion Height Adjusting Washer"andRFD-17, "Backlash".
Backlash
1. Remove carrier cover. Refer toRFD-19, "Differential Assembly".
2. Check drive gear to drive pinion backlash using a dial indicator
at several points.
3. If outside the standard, adjust side bearing adjusters.
CAUTION:
Check tooth contact and total preload after adjusting side
bearing adjusters. Refer toRFD-16, "
Total Preload Torque",
RFD-16, "
Tooth Contact".
a. Remove adjuster lock plates.
b. Loosen side bearing cap bolts.

c. Tighten or loosen each side bearing adjusters using Tool.
d. In case of excessive backlash, loosen side bearing adjuster A
and tighten side bearing adjuster B. In case of insufficient back-
lash, loosen side bearing adjuster B and tighten side bearing
adjuster A.
e. After adjusting backlash, tighten side bearing cap bolts to the
specified torque. Refer toRFD-15, "
COMPONENTS".
f. Install adjuster lock plates and tighten to the specified torque.
Refer toRFD-15, "
COMPONENTS".
Companion Flange Runout
1. Fit a dial indicator onto companion flange face (inner side of pro-
peller shaft bolt holes).
2. Rotate companion flange to check for runout.
3. Fit a test indicator to the inner side of companion flange (socket
diameter).
4. Rotate companion flange to check for runout.
5. If the runout value is outside the repair limit, follow the procedure
below to adjust.
a. Check for runout while changing the phase between companion flange and drive pinion by 90°,180°and
270°and search for the point where the runout is the minimum.
b. If the runout value is still outside of the limit after the phase has been changed, replace companion flange.
c. If the runout value is still outside of the limit after companion flange has been replaced, check drive pinion
front bearing, drive pinion rear bearing and drive pinion assembly.Tool number : KV38108800
